Pros
Pro Beastly performance
The laptop includes two GeForce GTX 980M graphics cards connected over SLI. As of March, 2015 the 980M is the most powerful graphics card and connecting two over SLI almost doubles laptop's graphics performance.
In the real world, having two GTX 980M GPUs over SLI allows running Far Cry 4, Shadow of Mordor, Battlefield 4 on ultra settings at 113, 116, and 124 fps on average respectively.
It also includes the best (as of March, 2015) mobile CPU available - the i7-4980HQ.
Can be configured to have up to 32 GB of RAM, although anything past 16 GB for gaming is overkill.
The laptop has 1TB of HDD and 1 TB of SSD. Files read from SSD will load quicker so it's recommended for the operating system and software or games that are run regularly or can take advantage of the quicker load times.
Pro Has a mechanical keyboard and a hybrid touchpad/numpad
This is the first gaming laptop to put in a full mechanical keyboard from SteelSeries. It has MX Cherry Brown switches and is positioned more to the front of the laptop as to mimic a typical desktop experience. To accommodate the position, touchpad was moved to right of the keyboard. By tapping a light in the corner it can be turned into a numpad.
